when you walk; wheels roll to move cars; you grasp something in your hand; cars brake; these are all because of friction. Really there are advantages of friction.
Friction is quiet useful at the same time. Without friction just imagine, you won't be able to hold anything in your hand, without friction there is no such thing to hold two surfaces together and remain in contact. Cars would start flying and would be stable on the road, and simply you can't hold your girlfriend's hand and walk.
Friction and gravity.
The flexibility of friction ridge skin means that no two finger or palm prints are ever exactly alike in every detail; even two impressions recorded immediately after each other from the same hand. Fingerprint identification, also referred to as individualization, involves an expert, or an expert computer system operating under threshold scoring rules, determining whether two friction ridge impressions are likely to have originated from the same finger or palm (or toe or sole). :)
Ridge hand is done with either the left or right hand. The act of ridge hand is done with the entire hand and all fingers extended forward with the thumb extended along the length of the hand and tucked into the palm. The little finger does not lead the ridge hand.

put ur hand on the table. move hand from rest horizontally on table. initial friction is static, once moving its called kinetic friction

Rubbing causes friction, friction creates heat.
With hand-driers there is no friction or rubbing (as there would be with a towel).

Friction, resulting in heat
increasesBy increasing the friction between your hand and the lid, you transmit more torque to the lid which allows you to unscrew it. If friction is too low, then your hand will just slip instead of turning the lid.
